IEC:2001 5 INTRODUCTION Recent progress in the battery i
30、ndustry has seen secondary lithium cells and batteries evolve from the research environment to a state of regular commercial production and sale. In response to this situation, the IEC has prepared a new standard to cover secondary lithium cells and batteries for portable electronic applications. Th
31、is part of IEC 61960 covers secondary lithium batteries and must be used in conjunction with IEC 61960-1, which covers secondary lithium cells. This standard has been prepared so that it covers only those secondary lithium batteries that are: ? commercially available, and ? available from two or mor
32、e manufacturers. Traditionally the manufacturers and users of alkaline secondary cells and batteries have expressed the current used to charge and discharge these cells and batteries as a multiple of the capacity. For example, a current of 20 A used to charge a cell with a rated capacity (C Ah) of 1
33、00 Ah would be expressed as C/5 A or 0,2 C A. This method of current designation was originally used in earlier standards relating to alkaline secondary cells and batteries. Comments have been made, that this method of current designation is dimensionally incorrect in that a multiple of the capacity
34、 (ampere hours) will be in ampere hours and not, as required for current, in amperes. As a result of these comments, the method described in IEC 61434 has been used in this standard. In brief, the method states that the reference test current (It) is expressed as: ItA = Cn Ah/1h where Cn is the rate
35、d capacity declared by the manufacturer in ampere hours (Ah), and n is the time base in hours (h) for which the rated capacity is declared. 5 egaP 1002:206916 NE BSI 15 March 2002 Page 5 EN 619602:2001 Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 10 15:09:04 GMT+00:00 2006, Uncontrolled Copy,

IEC:2001 6 SECONDARY LITHIUM CELLS AND BATTERIES FOR PORTABLE APPLICATIONS Part 2: Secondary lithium batteries 1 General 1.1 Scope This International Standard specifies performance and safety tests, designations, markings, dimensions and other requirements for secondary lithium ba
37、tteries. The objective of this standard is to provide the purchasers and users of secondary lithium batteries with a set of criteria with which they can judge the performance and safety of various secondary lithium batteries offered by various manufacturers. This standard defines a minimum required
38、level of performance and safety, and a standardized methodology by which testing is performed and the results of this testing reported to the user. Hence, users will be able to establish the viability of commercially available batteries via the declared specification and thus be able to select the b
39、attery best suited for their intended application. This standard covers secondary lithium batteries with a range of chemistries. Each electrochemical couple has a characteristic voltage range over which it releases its electrical energy, a characteristic nominal voltage and a characteristic final vo
40、ltage during discharge. Users of secondary lithium cells and batteries are requested to consult the manufacturer for advice. For the avoidance of doubt, the scope of this standard does not include secondary lithium cells which are covered in IEC 61960-1. 1.2 Normative references The following normat
41、ive documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 61960. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IEC 61960 are encoura
42、ged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
